1. Field of the Invention
The present invention relates to an automobile sunroof, and more particularly to an automobile sunroof able to block the sunlight.
2. Description of the Prior Art
A conventional sunroof includes a glass panel. In general, the glass panel is transparent, allowing the sunlight to enter the passenger compartment. When the user wants to block the sunlight, the glass panel is provided with a shelter, such as a screen, a shading panel or sheathing paper.
Although the shelter of the sunroof has the effect to block the sunlight, it is inconvenient for use. The light transmittance of the glass panel of the sunroof is fixed, and it cannot be adjusted according to the demand of the user or the weather. Accordingly, the inventor of the present invention has devoted himself based on his many years of practical experiences to solve these problems.
The primary object of the present invention is to provide an automobile sunroof having a smart electronic screen. The light transmittance of a liquid crystal film can be adjusted as desired, providing a shading effect to enhance the comfort of riding.
In order to achieve the object, the automobile sunroof having a smart electronic screen of the present invention comprises a sunroof main body, a liquid crystal film, a controller, a first input unit, and a power source. The sunroof main body is disposed in the roof of a car. The sunroof main body includes a first glass panel. The liquid crystal film is disposed underneath the first glass panel. The controller is connected with the liquid crystal film. The first input unit is connected with the controller. The power source is externally connected on the liquid crystal film and connected with the controller. The power source supplies electric current to the liquid crystal film.
By the first input unit to transmit a signal to the controller, the liquid crystal film is controlled by the controller to adjust the light transmittance of the liquid crystal film. When the user wants to adjust the degree previous to light for the sunroof main body, he/she can make an adjustment as desired to change the light transmittance of the liquid crystal film, providing a shading effect to enhance the comfort of riding.
Embodiments of the present invention will now be described, by way of example only, with reference to the accompanying drawings.
The sunroof main body 10 is disposed in the roof of a car. The sunroof main body 10 includes a first glass panel 11. In this embodiment, the first glass panel 11 is a transparent glass. The color of the transparent glass can be changed.
The liquid crystal film 20 is disposed underneath the first glass panel 11 in a coating or attached manner. The light transmittance of the liquid crystal film 20 is 30%. The liquid crystal film 20 is transparent when not electrified, and it is opaque when electrified.
The controller 30 is connected with the liquid crystal film 20.
The first input unit 40 is connected with the controller 30. The first input unit 40 is a touch panel or a micro adjustment switch.
The second input unit 50 is connected with the controller 30. The second input unit 50 is a sensor. The sensor is a photoresistor.
The power source 60 is externally connected on the liquid crystal film 20, and connected with the controller 30. The power source 60 supplies electric current to the liquid crystal film 20. The power source 60 can be common mains power, solar power, or battery power. The way for the power source 60 to supply power can be wireless or wired.
In addition to the first input unit 40 to adjust the light transmittance of the liquid crystal film 20 for the automobile sunroof having a smart electronic screen, the user can start the second input unit 50. When the photoresistor senses the sunlight, it will send a signal to the controller 30. The controller 30 further controls the power source 60. When the sunlight is blazing, the light transmittance of the liquid crystal film 20 will be decreased. When the sunlight is weak, the light transmittance of the liquid crystal film 20 will be increased. Accordingly, the light transmittance of the liquid crystal film 20 can be changed according to the sunlight.
It is noted that the liquid crystal film 20 of the automobile sunroof having a smart electronic screen is attached to the glass panel. If the glass panel is broken by impact, the cullet will be stuck to the liquid crystal film 20 to form a net pattern and won't be exploded to hurt the user. The present invention provides an explosion-proof effect.
It is noted that the increase of the light transmittance of the liquid crystal film 20 is able to block the sunlight and to lower the temperature in the car.
Although particular embodiments of the present invention have been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the present invention. Accordingly, the present invention is not to be limited except as by the appended claims.
